This formula gives T ≈ 131 years for replacement of gasoline and diesel. The proposed market-expectations approach may allow policymakers to effectively develop policies and plan for long-term changes.

"The 2010 edition of the World Energy Outlook (WEO) was released on 9 November and it provides updated projections of energy demand, production, trade and investment, fuel by fuel and region by region to 2035. It includes, for the first time, a new scenario that anticipates future actions by governments to meet the commitments they have made to tackle climate change and growing energy insecurity@

The study prepared by the European and international climate experts at PricewaterhouseCoopers LLP, the European Climate Forum, the Potsdam Institute for Climate Impact Research and the International Institute for Applied System Analysis, examines the potential for powering Europe and North Africa with renewable electricity exclusively by 2050 and the opportunities this transformation to the power sector presents. The study provides policy makers and business leaders with clear direction and a step wise approach on how to achieve the 2050 vision.

The Roadmap 2050 project sets out the crucial role of a zero-carbon power sector to Europe’s long-term climate commitments and shows different pathways that can make this a reality delivering economic and energy security goals. The Roadmap is based on extensive technical, economic and policy analyses conducted by five leading consultancies: Imperial College London, KEMA, McKinsey & Company, Oxford Economics, and the Office of Metropolitan Architecture, in addition to the involvement of utilities, transmission operators and NGOs.

On 30th April 2009, UKERC released its ambitious report addressing two of the Government's toughest energy policy goals – delivering reliable energy to consumers while meeting its legal commitment to reduce C02 emissions by 80% by 2050.

Interesting article over on Wired about Kirk Sorensen and the community served by his Energy From Thorium blog. To hear these people tell it, thorium fission in fluid fuel reactors offers an idyllic vision of a boundless-energy-from-the-atom type future no one has really believed in since the early 50s. Thorium, reportedly, is abundant, safe, highly efficient as a nuclear fuel, and produces waste that is radioactive only for a few hundred years instead of tens of thousands.

However researchers at the National Renewable Energy Laboratory estimate that Indium's availability is likely to constrain the manufacturing of CIGS once production reaches the tens of gigawatts level, unless levels of recovery during extraction are increased.

According to the European Commission, Europe's power plants are getting older and, combined with growing demand for energy, Europe will need 360 GW of energy from new sources in the next 12 years - this is equal to 50% of current energy capacity in the EU. The EWEA thinks that 40 GW of this energy can be produced by offshore wind.

The book Sustainable Energy – Without the Hot Air by David J.C. MacKay is a unique case among all of the current publications on this topic. If every author and decision maker involved with climate change and energy issues would take this book as a starting point before making any claims or proposals, the world would be saved a huge amount of discussion-energy, energy-to-disentangle-confusion, and energy-spent-on-fruitless-efforts.

Nearly 50% of global electricity supplies must come from renewable energy sources in order to cut CO2 emissions in half by 2050, the International Energy Agency (IEA) says in its latest study, “Deploying Renewables: Principles for Effective Policies.”
